something I’ve wanted to do for a long time and never got around to it …
Just give a try, it’s public available: https://bgp.stoege.net/
OpenBSD got their own HTTP Daemon in Base System. Let’s enable and configure it.
Regex is cool. But have you ever tried to grep IPv4 / IPv6 Adresses from a File or extract from a bunch of data ? Did you use Google Search and found lot of Links, Tip’s and Examples ? And non of them worked well ?
I can highly recommend CyberChef for stuff like that … https://gchq.github.io/CyberChef/
If you wanna use Regex in your own Scripts, here is a little Extract from Cyberchef.
We’re all dealing with MAC Addresses, some times … there are different formats on different systems. this little script convert it to all formats and you can choise the appropriate ones.
$ maconvert aa:bb:cc:dd:ee:ff
aabbccddeeff
aa:bb:cc:dd:ee:ff
aa-bb-cc-dd-ee-ff
aabb.ccdd.eeff
Copy/Paste will work on OpenBSD, Linux needs some small Modifications (as there is no doas for example …)

assuming you have a apu2|apu3|apu4 from pcengines or a virtual machine running on KVM/Qemu. And you don’t have vga/dvi/hdmi whatever kind of video output. of course, you can install and run OpenBSD (or Linux) on this boxes.
write openbsdxx.img to an USB Stick. On MacOS, you can use Balena Etcher for example.
if you wanna install from an USB Stick, set the correct Port and Speed before booting.
